Description James Courtier-Dutton 2006-10-08 14:34:10 UTC 
Most recent kernel where this bug did not occur:
Distribution: 2.6.18 patched with rt5 realtime patches.
Hardware Environment: Pentium 4
Software Environment: Linux
Problem Description:
System hangs with masses of output on the console rolling past.
Problem not present in 2.6.17.11.

Steps to reproduce:
Boot to a terminal login.
modprobe netconsole netconsole=@192.168.0.10/,@192.168.0.255

Use sysreq-S to try a sync of the HD.
System hangs.
The system in fact hangs on the first kernel log entry needing to be sent to the
netconsole.

does the problem persist on 2.6.18-rt7 ?
